In addition, the voice pre-processing unit 624 performs a process of extracting a voice feature amount for the target sound.

(2-3-2-1) Image Preprocessing Unit The image preprocessing unit 622 extracts a human whole body region image from the image data acquired by the acquisition unit 610, for example. For example, the image preprocessing unit 622 uses a difference image between image data and a background image stored in advance in the storage unit 670, a difference image between an image at a certain point in time and an image a predetermined time before that point, or the like. Then, a moving object region in which the image is changing (region where the moving object is considered to be captured) is extracted. Then, the image preprocessing unit 622 sets the moving object region (or a group of moving object regions considered to be caused by the same object) and the aspect ratio as a human region when the size and aspect ratio match the human body condition. The image of this part is extracted as a person whole body region image. The image pre-processing unit 622 obtains time-series human whole body region image data by performing such processing. In addition, when the distance between the person whole body region image at a certain point in time and the person whole body region image a predetermined time before that point is within a predetermined distance, the image preprocessing unit 622 converts the person whole body region image from the same person. A tracking process can be performed by associating with a thing.

  Note that the method for extracting a person whole body region image is not limited to the method described here. For example, matching processing with a person template, color information (skin color) or the like if the image is a color, etc. The person whole body region image may be extracted using. As another method, a person whole body region image may be extracted by further using information obtained by a device different from the camera 410 (for example, an infrared image obtained by an infrared camera). Also, other known methods may be used for extracting the human whole body region image. Further, the tracking processing method is not limited to the method described here, and a known method may be applied.

  Note that the image pre-processing unit 622 performs, in addition to the process of extracting the person whole body region image from the image data, or in place of this process, from the image data acquired by the acquisition unit 610 of the person in the target space R. A local image (for example, an image of only a face or an image of only arms or legs) may be extracted as a person local region image. Various known methods may be used to extract the local region of the person in the image.

  Note that what kind of image the image pre-processing unit 622 extracts is learned so that the discriminator 626 described later determines the activity state and mood of a person in the target space R based on what input. It may be determined according to whether or not.

(2-3-2-2) Voice Pre-Processing Unit The voice pre-processing unit 624 detects the target sound section, and from the sound data including the target sound and noise, the section where the target sound exists and the other sections And a space where the target sound exists is extracted. For example, the sound preprocessing unit 624 detects this section as the target sound section when a state of a predetermined volume or higher continues in the sound data for a predetermined time or longer. However, the target sound segment detection method is not limited to such a method, and various known methods may be used.

  The voice preprocessing unit 624 extracts a voice feature amount from the target sound while referring to an acoustic model (not shown). The audio feature amount is not limited, and is, for example, volume, tempo, tone, meaning of audio, and the like. Note that the speech preprocessing unit 624 converts speech into text by referring to a word pronunciation model and a language model (not shown) in addition to the acoustic model, and recognizes the meaning of the speech. For voice recognition by the voice preprocessing unit 624, various known methods may be used.

(2-3-2-2-3) Discriminator The discriminator 626 includes information related to an image (particularly, a person whole body region image and / or person local region image here) and / or information related to a sound (particularly here, a voice feature amount). The learning process is performed so as to output a person's activity state or mood as a determination result when the character is input. In the present embodiment, the classifier 626 is subjected to learning processing by machine learning. Here, machine learning is not based on a rule base (even if rules for judgment etc. are not given in advance), but learning based on given information and autonomously making rules for judgment. It means a technology / method that can be found.

  In addition, when the discriminator 626 discriminates with respect to different inputs, the discriminator 626 may be composed of a plurality of discriminators. For example, the classifier 626 determines the activity state and mood of a certain person from only information about the image, determines the activity state and mood of another person from only the information about sound, and relates to the image. When the activity state and mood of another type of person are further determined from the information related to the information and the sound, the discriminator 626 may be composed of a plurality of discriminators that perform discrimination for different inputs.

  The discriminator 626 has been learned by supervised learning, for example. Here, supervised learning is a machine that causes the discriminator 626 to learn by providing data (teacher data) in which an input and a correct answer (human activity state or mood) corresponding to the input are associated with each other. Means learning method.

  For example, the learning classifier 626 is provided with a lot of data as teacher data in which an image of a person is associated with the activity state or mood of the person when the image is taken. Note that the human image here may be an image of a person's whole body (an image corresponding to a person whole body region image) or a local image of a person (an image corresponding to a person local region image). Alternatively, it is only necessary to select an image that can be used to determine the activity state and / or mood of a person. In addition, the human image here may be a moving image or a still image. The learning discriminator 626 has a lot of data as teacher data in which the voice feature amount of sounds generated by various persons and the activity state or mood when the persons are generating the sounds are associated with each other. Provided. In addition, in addition to these data or instead of these data, the classifier 626 that is currently learning has various human images and sound feature amounts of sounds generated by the human when the images are captured, and images. A large number of data relating the activity state or mood of the person at the time of imaging may be provided as teacher data.

  Note that, for example, in the case of determining the activity state and mood of a person only with respect to a certain individual, the classifier 626 that is learning includes the image / sound of the individual and the activity state of the person or Teacher data associated with mood may be provided. On the other hand, when the classifier 626 is versatile, the learning classifier 626 is provided with teacher data that associates various people's images / generated sounds with their activities or moods. It is preferred that

  The learning algorithm used by the classifier 626 is, for example, a neural network (including deep learning), but may be another known machine learning algorithm (for example, SVM (Support Vector Machine)). Note that, as described above, when the classifier 626 has a plurality of classifiers for identifying different inputs, processing described below is divided into a plurality of processes, and each of the divided processes is different. In the case of being executed by a discriminator, different learning algorithms may be used for learning of each discriminator.

  When the determination unit 620 receives the human whole body region image and / or the human local region image extracted by the image preprocessing unit 622 and / or the audio feature amount extracted by the audio preprocessing unit 624, the determination unit 620 Using the vessel 626, the activity state or mood of the person in the target space R is determined. That is, for example, the determination unit 620 is learned based on the person whole body region image extracted by the image preprocessing unit 622 (based on the whole body movement of the person in the target space R acquired by the image acquisition unit 612). Using the discriminator 626, the activity state or mood of a person in the target space R is determined. For example, the determination unit 620 determines the activity state or mood of the person in the target space R using the learned classifier 626 based on the change in the posture of the person in the target space R acquired by the image acquisition unit 612. To do. In addition, the determination unit 620 has learned, for example, based on the person local region image extracted by the image preprocessing unit 622 (based on the local movement of the person in the target space R acquired by the image acquisition unit 612). The activity state or mood of the person in the target space R is determined using the discriminator 626. For example, the determination unit 620 learns based on the movements of the facial muscles (for example, between the eyebrows and around the mouth) of the target space R acquired by the image acquisition unit 612 and the movements of the muscles of the hands and legs of the target space R. The activity state or mood of the person in the target space R is determined using the already-identified classifier 626. Note that the determination unit 620 is not limited to the whole body or local movement of the person in the target space R acquired by the image acquisition unit 612, but also a certain instantaneous state (for example, a pose taken by a person, facial expression, Even if the activity state or mood of a person in the target space R is determined using the learned discriminator 626 based on the color of the eyelid or the hue or the change thereof (for example, the face is flushed). Good. In addition, the determination unit 620, for example, based on the audio feature amount extracted by the image preprocessing unit 622 (based on the sound emitted by the person in the target space R acquired by the sound acquisition unit 614), the learned classifier The activity state or mood of the person in the target space R is determined using 626.

  Note that the determination unit 620 is further based on information other than the person whole body region image and / or the person local region image extracted by the image preprocessing unit 622 and / or the sound feature amount extracted by the sound preprocessing unit 624. You may judge the activity state and mood of the person who exists in the object space R.

  For example, the determination unit 620 determines a state in which a person has entered the target space R using the person whole body region image or the like extracted by the image preprocessing unit 622 (returning home state to the house A). The information on the outdoor temperature to be measured may be used to determine the state where a person who has returned home from a cold space has entered the target space R.

(2-3-3) Scent Determination Unit The scent determination unit 630 determines the scent pattern of the scent discharger 300 based on the determination result of the determination unit 620 (the activity state or mood of a person in the target space R). . In addition, the scent determining unit 630 further determines the scent of the scent discharger 300 based on the measurement result of the temperature of the target space R detected by the temperature sensor 14 and / or the measurement result of the humidity of the target space R detected by the humidity sensor 16. It is preferable to determine the pattern. Here, the scent determining unit 630 determines the scent pattern of the scent discharger 300 based on the activity state or mood of a person in the target space R, the temperature of the target space R, and the humidity of the target space R.

  Specifically, the scent determining unit 630 determines the scent pattern of the scent discharger 300 based on information stored in the correspondence information database 672 of the storage unit 670 described later. Here, the information stored in the correspondence information database 672 is the combination of the activity state or mood of the person in the target space R, the temperature of the target space R, and the humidity of the target space R, and the scent pattern of the scent discharger 300. (See FIG. 4). In the list of FIG. 4 shown as an example, the temperature / humidity is divided into three levels of high / medium / low at a predetermined threshold, and the temperature / humidity level is related to each of the activity state and mood of the person in the target space R. A scent pattern is prepared for each combination.

(2-3-4) Scent discharger control unit When the scent determining unit 630 determines a scent pattern, the scent discharger control unit 640 uses the scent discharger 300 to generate a scent according to the determined scent pattern. The scent discharger 300 is controlled to release to R.

  Specifically, when the scent determining unit 630 determines a scent pattern, the scent discharger control unit 640 refers to the pattern database 674 of the storage unit 670. The pattern database 674 is a list that stores, for each scent pattern, a scent type, a scent release amount (a fragrance release amount per unit time), and a scent release time (see FIG. 6). The scent discharger control unit 640 reads the scent type, the scent release amount, and the scent release time corresponding to the scent pattern determined by the scent determination unit 630, and the scent release unit 300 operates under the read conditions. The scent discharger 300 is controlled as described above.

  The scent discharger control unit 640 may control the scent discharger 300 so that the scent discharger 300 releases the scent only when the air conditioner 100 is in operation.

  Conversely, the scent discharger control unit 640 may control the scent discharger 300 so that the scent discharger 300 releases the scent even when the air conditioning apparatus 100 is stopped. In addition, when operating the scent discharger 300 while the air conditioning apparatus 100 is stopped, the scent discharger control unit 640 may request the controller 50 of the air conditioning apparatus 100 to operate the indoor fan 12.

(2-3-5) Change learning unit The change learning unit 650 learns a change in a person's activity state and / or mood before and after the scent discharger 300 releases a scent according to a scent pattern. Specifically, the change learning unit 650 determines the scent pattern determined by the scent determining unit 630 and the activity state and / or mood of the person before and after the scent discharger 300 releases the scent according to the scent pattern. The changes are associated with each other and stored in the change database 676 of the storage unit 670.

  More specifically, when the scent determining unit 630 determines the scent pattern, the change learning unit 650 determines the activity state or mood of the person in the target space R used by the scent determining unit 630 for determining the scent pattern. The change database 676 of the storage unit 670 stores the activity state or mood of the person in the target space R before the scent discharger 300 releases the scent into the target space R. In addition, when the scent discharger 300 releases the scent into the target space R, the change learning unit 650 determines the activity state or mood of the person in the target space R determined by the determination unit 620 after a predetermined time from the start of release. 300 is stored in the change database 676 of the storage unit 670 as the activity state or mood of the person in the target space R after releasing the scent into the target space R.

  In addition, it is preferable that the change learning part 650 performs the learning suitable for evaluation of the effect of a fragrance. For example, as a result of the change learning unit 650 determining that the mood of the person in the target space R is sleepy, the scent discharger 300 scents the target space R with a scent pattern determined based on the mood. When released, it is preferable to learn whether the mood of the person in the target space R has changed to a sleepless state (whether it is determined that the person is sleepy). In addition, the change learning unit 650 determines, for example, that the mood of the person in the target space R is in a moody or depressing state. When the scent is released, it is preferable to learn whether the mood of the person in the target space R has changed to a state of good mood (whether it is determined that it is unwell or depressed). In addition, the change learning unit 650 determines that the activity state of the person in the target space R is, for example, when waking up, and the scent discharger 300 enters the target space R with a scent pattern determined based on the activity state. If the scent is released, whether the mood of the person in the target space R has changed to a sleepless state (whether it is determined that the person is in a sleepy state), or has the activity status of the person in the target space R changed to a working state? It is preferable to learn.

  Note that the change learning unit 650 constantly learns the activity state and / or mood change of the person in the target space R before and after the scent discharger 300 releases the scent into the target space R according to the scent pattern. There is no need. For example, the change learning unit 650 may be configured to perform learning only when the activity state or mood of a person in the target space R used by the scent determining unit 630 to determine the scent pattern is a predetermined type. Good.

  The information learned by the change learning unit 650 and stored in the change database 676 of the storage unit 670 is displayed on a display unit (not shown) provided in the remote controller 30, for example. The information learned by the change learning unit 650 and stored in the change database 676 of the storage unit 670 may be transmitted to the user's portable information terminal, computer, or the like. In addition, instead of presenting the information stored in the change database 676 to the user as it is, the control device 600 makes a recommendation on how to change the control derived based on the information stored in the change database 676. May be presented. When the user who saw the information does not have a sufficient effect of a certain scent pattern (for example, when there is no change in sleepiness even when the scent is released), the user stores it in the pattern database 674 from the input unit 660 described later. The information stored in the correspondence information database 672 can be changed as appropriate.

  Further, the change learning unit 650 may automatically change the information stored in the pattern database 674 or the information stored in the correspondence information database 672 based on the learning result.

  For example, when the effect of a certain scent pattern is not sufficient (for example, when there is no change in sleepiness even when a scent is released), the change learning unit 650 stores information (scent type). Or the amount of fragrance | flavor discharge | release, the discharge | release time of fragrance | flavor) may be rewritten suitably. Specifically, when the scent discharger 300 emits a scent and the human sleepiness does not change, the change learning unit 650 causes the scent releaser 300 to have a stronger type of scent or a stronger scent. Information stored in the pattern database 674 may be rewritten so as to release a (dense) scent.

  In addition, for example, when the effect of a certain scent pattern is not sufficient (for example, when there is no change in sleepiness even when a scent is released), the change learning unit 650 appropriately stores information stored in the correspondence information database 672. You may rewrite it. Specifically, the change learning unit 650 releases the scent after the rewriting of the correspondence information database 672 compared to before the rewriting when the scent discharger 300 releases the scent and the human sleepiness does not change. The information stored in the correspondence information database 672 may be rewritten so that the vessel 300 emits a strong scent under the same conditions (in the same person's activity state or mood, the same temperature, and the same humidity).

(2-3-6) Input Unit The input unit 660 is a functional unit that receives a user instruction for the scent discharger 300. For example, the input unit 660 receives instructions such as on / off of the scent discharger 300, automatic operation / manual operation of the scent discharger 300, and the like. In the scent discharge system 1, when the input unit 660 receives an instruction for automatic operation of the scent discharger 300, the scent determination unit 630 determines the scent pattern of the scent discharger 300 based on the determination result of the determination unit 620. Then, the scent discharger 300 releases the scent according to the determined scent pattern to the target space R. In addition, description is abbreviate | omitted regarding operation | movement of the scent discharger 300 when the scent discharger 300 is manually operated here.

  In addition, the control device 600 is preferably configured to be able to rewrite information stored in the correspondence information database 672 and information stored in the pattern database 674 based on user input to the input unit 660. That is, the control device 600 is configured to be able to change which scent pattern is used for the activity state or mood of a person in the target space R, and the temperature and humidity of the target space R by a user input to the input unit 660. It is preferable. In addition, the control device 600 is configured to be able to change which type of scent is emitted in what amount and how long in a certain scent pattern by a user input to the input unit 660. It is preferable.

  The correspondence information database 672 and the pattern database 674 preferably store default data in advance. FIG. 5 is a list showing what kind of fragrance is generally suitable for the activity state and mood of a person in the target space R. The correspondence information database 672 and the pattern database 674 store default data based on information as shown in FIG. However, since the scent has personal likes and dislikes, it is preferable that the information in the correspondence information database 672 and the pattern database 674 can be changed by input from the input unit 660 as described above.

  Note that the control device 600 may not be able to rewrite all the information stored in the correspondence information database 672 and the pattern database 674. For example, the control device 600 may be configured so that only the type of scent emitted by the scent discharger 300 can be changed by an input from the input unit 660 according to a certain activity state or mood of a person in the target space R. Good.

(2-3-7) Storage Unit The storage unit 670 stores various types of information used in the control device 600. For example, the storage unit 670 stores the image and sound of the target space R acquired by the acquisition unit 610.

  The storage unit 670 includes a correspondence information database 672, a pattern database 674, and a change database 676 as information storage areas. Since the information stored in the correspondence information database 672, the pattern database 674, and the change database 676 has already been described, the description thereof is omitted here.

(3) Scent Control of the Target Space The scent control of the target space R by the scent discharge system 1 will be described with reference to FIG. In addition, the flowchart demonstrated here is an example of a control flow, Comprising: A control flow is not limited.

  Here, the determination unit 620 uses the human information acquired by the acquisition unit 610 every predetermined time (for example, the image captured by the camera 410 and the sound acquired by the microphone 420 during the previous predetermined period (for example, 10 seconds)). Based on this, the activity state and / or mood of a person in the target space R is determined. The predetermined time may be a relatively short time (for example, every minute) or may be a relatively long time (for example, every 30 minutes). In addition, here, the determination unit 620 determines “not applicable” when the human information acquired by the acquisition unit 610 does not apply to any activity state or mood of the person to be determined. And

  At a certain timing (in step S1), it is assumed that the determination unit 620 makes a determination other than “not applicable” with respect to the activity state or mood of the person in the target space R based on the human information acquired by the acquisition unit 610. . For example, here, it is assumed that the determination unit 620 determines that the person in the target space R feels sleepy. The determination result of the determination unit 620 is notified to the scent determination unit 630.

  When the determination result is notified from the determination unit 620, the scent determining unit 630 acquires the temperature of the target space R measured by the temperature sensor 14 and the humidity of the target space R measured by the humidity sensor 16 (step S2). ).

  Next, the scent determining unit 630 determines the scent pattern of the scent discharger 300 based on the activity state or mood of the person in the target space R, the temperature of the target space R, and the humidity of the target space R. (Step S3). Specifically, the scent determining unit 630 determines the scent pattern of the scent discharger 300 based on information stored in the storage unit 670 (information in the correspondence information database 672, here, the list in FIG. 4).

  More specifically, the scent determining unit 630 compares the temperature of the target space R with a threshold value, and the temperature of the target space R is in any of the high / medium / low stages in the list of FIG. Determine whether it corresponds. Further, the scent determining unit 630 compares the humidity of the target space R with a threshold value, and determines whether the humidity of the target space R corresponds to the high / medium / low level in the list of FIG. to decide. For example, here, the temperature of the target space R corresponds to the “medium” stage in the list of FIG. 4, and the humidity of the target space R corresponds to the “medium” stage in the list of FIG. Assume that it has been judged. Next, the scent determining unit 630 refers to the list of FIG. 4, and determines the activity state or mood (here sleepy state) of the person in the target space R determined by the determining unit 620 and the temperature of the target space R. A pattern (here, “pattern 5”) corresponding to the stage (here “medium”) and the humidity level of the target space R (here “medium”) is specified, and this pattern is defined in the scent discharger 300. Determined as a scent pattern.

  Next, in step S4, the scent discharger control unit 640 controls the operation of the scent discharger 300 with the scent pattern determined by the scent determination unit 630. Specifically, the scent discharger control unit 640 refers to the storage unit 670 (pattern database 674, here, the list of FIG. 6), and the scent type and fragrance corresponding to the scent pattern determined by the scent determination unit 630 The amount of release and the release time of the scent are specified. For example, when the scent pattern determined by the scent determining unit 630 is “pattern 5”, the scent discharger control unit 640 refers to the list of FIG. The time is specified as “herbal”, “b2” and “T1”. And the scent discharger control part 640 controls operation | movement of the scent discharger 300 with this specified content. That is, the scent discharger control unit 640 controls the operation of the scent discharger 300 so as to release the “herb-based” scent perfume over the “T1” time by the release amount “b2” per unit time.

  Next, when a predetermined time elapses after the scent discharger 300 starts to emit scent under the control of the scent discharger control unit 640, the acquisition unit 610 acquires human information regarding the activity state and mood of the person in the target space R. (Step S5). Specifically, the image acquisition unit 612 acquires the image data of the target space R transmitted from the camera 410 (for example, the image data of the last 10 seconds), and the sound acquisition unit 614 is the target transmitted from the microphone 420. Sound data in the space R (for example, sound data for the last 10 seconds) is acquired. Note that the timing at which the acquisition unit 610 acquires the human information may be during the release of the scent of the scent discharger 300 or after the scent releaser 300 has released the scent (for example, the scent releaser 300 here). It may be after “T1” time has elapsed since the start of releasing the scent.

  Next, in step S <b> 6, the determination unit 620 determines the activity state and / or mood of a person in the target space R based on the person information acquired by the acquisition unit 610.

  Next, in step S <b> 7, the change learning unit 650 learns a change in human activity state and / or mood before and after the scent discharger 300 releases a scent according to the scent pattern. Specifically, the change learning unit 650 determines the scent pattern determined in step S3 and the activity state or mood before and after the scent discharger 300 releases the scent (the determination result in step S1 and the determination result in step S6). Are stored in the change database 676 of the storage unit 670. Further, as described above, the change learning unit 650 may appropriately rewrite the contents of the correspondence information database 672 and the pattern database 674 based on the learning result.

  After the end of step S7, the determination unit 620 again determines the activity state or mood of the person in the target space R based on the human information acquired by the acquisition unit 610 every predetermined time. Then, when the determination unit 620 determines other than “not applicable” for the activity state or mood of the person in the target space R based on the human information acquired by the acquisition unit 610, a series of steps after step S2 is performed again. Is executed.
